I have used the Spocal excel spreadsheet to determine my spoke needs and just placed a big order! Can't wait to get my hands on that big beefy Alex rim!

One final question - I purchased 2.00x12mm brass nipples. What is the correct spoke wrench size for these? Can't find that anywhere...

Thanks all

Spoke wrench/nipple fit isn't totally about the thread size. There are small differences in the width across the flats among brands. So 14g spoke wrenches came in 3 basic sizes, with DT being the smallest, and generic Italian nipples the largest. Unfortunaely the tolerance in spoke wrench sizes is about as much as the difference between the various nipples, so I keep spoke wrenches in a variety of sizes, and use whichever fits tightest regardless of whether it's the "right" one.
